Applications of Spin Coating of Polymer Precursor and Slurry Suspensions for Solid Oxide Fuel Cell Fabrication

In this paper a ceramic deposition method that does not require a high temperature sintering step is presented. The method is used for a fabrication of electrolyte layers for SOFCs and high temperature protective coatings of stainless steel. The preparation of polymeric precursors and ceramic slurries are described and structure evolution of the deposited layers during heat treatment is discussed. Application of described method might help in eliminating problems related to excessive steel corrosion of metal supported SOFCs or reaction between electrolyte and cathode during high temperature sintering process
